Turnbull encompasses approx. 16,000 acres of the Channeled Scablands. The ecosystem that predominates the Refuge is unique within the National Wildlife Refuge System. Forces of volcanism, glaciation and the largest flood in geological history have forged a distinct environment. Basalt outcrops, channeled canyons and ponderosa pine forests infused in a diverse landscape (130 marshes, wetlands and lakes) create an environment of beauty & a quality wildlife habitat. The acres of wetlands represent some of the last quality breeding habitat in eastern Washington for waterfowl.
Turnbull National Wildlife Refuge is located on the eastern edge of the Columbia Basin, in Spokane county in northeastern Washington. The Refuge is situated within the "Channeled Scablands", an area formed by glacial floods at the end of the last ice age. Turnbull National Wildlife Refuge was established in 1937 to provide productive breeding and nesting grounds for migratory birds and other wildlife
